- Paul Andersen explains how nutrients and water are transported in plants. He begins with a brief discussion of what nutrients are required by plants and where they get them. He shows you dermal, vascular and ground tissue in monocot and dicot roots, stems and leaves. He then explains how water is pulled up a tree in xylem and how sugar is pushed in a plant through phloem.

If any one deserves RUclips money, it's this guy.
Good plants for us
Indoor plants
seriously! he does such a good job. some videos I have a harder time, but in those times khan academy has been very helpful
ziji helium yup
ziji helium Ij
The way you explain things is so clear, and you add just a little bit of friendly humor which keeps things upbeat. you are a great teacher man, you inspire me.
Well said.
So true. His videos are so helpful
Aishah wrong explanation.
Happy teacher appreciation week! You have helped me a lot! From getting 50 to 90 percent on exams!
best teacher i have seen . my bio teacher teaches the same thing in 10 days and we dont understand. 14 mins here and i have the full concept.
ikr!? this man did a very good job presenting this. 10/10.
That says it all! I second that emotion.
It took my professor two semesters to teach our class this stuff and he didn't even get it correct. This 14 minute video is worth two full semesters of my horticulture college! Thanks for the video man!
Frank Phillips ... Hai frank I need guidance in filed study of horticulture . expecting Ur reply.
Frank Phillips hahahahahahah
The best teacher I have ever seen in my 15 years of education life.period.
our teacher really sickens me, he makes this subject so boring, cuz he hates his job probably and doesnt like teaching. But when I watch these videos I love it! :)
11:39 ''well these cells are empty, so how do you be alive and be empty'' Same.
gracias mr anderson for explaining this process clearly. This and all your videos have helped me a lot to understand how impressive and necessary plants are for our lives...muchas muchas gracias!!!!
you've saved my life so many times
facts me too
Hi, I find this video very useful for teaching, so thank you for creating it. One of my students just pointed out that at 3 minutes 42 seconds you have your pictures of monocotyledon and dicotyledon stem cross sections the wrong way round. The monocotyledon stem is the one with the scattered vascular bundles and the dicotyledon stem is the one with the bundles arranged in a ring.
Prof. Anderson videos are so great, he's such a hunk !
I've been relearning the concepts of biology after 20 years since graduating as a hobby. This guy has the best diagrams and explanations bar none.
I've been studying chemistry and botany for around a month now, and this is the BEST video I've come across on plant structure and function. Many Thanks. Great stuff.
the best teacher on youtube........
saved my butt over and over!
these video are so helpful my biology test is this Wednesday. Hope for the best:)
You explain things so plainly and efficient. MUCH better than my professor. Thank you :)
You are a good teacher of science
Really informative and also entertaining. Your teaching style keeps me attentive. Thank you! This has helped me in my college Plant Physiology course.
My garden is gonna rock after watching all these videos...
Last minute studying for the bio sat II subject tests tomorrow
I can relate
How did it go?
Lol, same!
did u pass
Same
A well deserved teacher. This video is awesome
I really enjoy your videos. I'm not in school right now, but I enjoy plants immensely and when I do get to school I want to major in plant biology or somewhere in the field of plants. Again, awesome video.
How can anyone dislike this???
These are our biology teacher who hate him because he is doing a better job then they do, takes him 14 minutes to explain something that takes a week at school
haters gonna hate
Angry Biology Teacher: "This guy is teaching better than me. So I don't like it"
botany is usually a pain mostly in high school but u make it fun!
Thank you Bozeman! Your videos are always so inciteful and very helpful.
I freakin love you Mr.Andersen
Thanks a million for this excellent presentation. This has been a huge help towards my RHS studies in the UK
last minute cram sesh. you have saved my life in this class, not joking ive learned more from your videos than a year from my teacher
This man deserves Nobel prize!! 🏆
God bless him. He truly deserves the world🌹❤️👏👏🙏
Now I understand the whole process of how water travels up to the leaves .. thanks
I'm studying for the Dental Admissions Test and you're videos have been very helpful!
Jacob Prows wait, what?
I have studied this stuff for ages. The water has a positive and negative charge within the plant cell walls.everytime the night time and day time go up and down the gravity pulls the plants waters and sugars over time within the xylem.
Tank you! I've always wondered how nutrients are being moved around in plants mechanically. No I know that and a bunch more!
It just makes since when he explains it🌼
As you can see, we've had our eye on you for some time now, Mr. Andersen.
This was amazing! Thank you for a clear summary and a clear diagram for the Phloem and Xylem transportation. You explained my proffs very confusing 5 power points clear as day.
I found the leaf structure very fascinating.
Watched your videos in AP bio and even in college, these videos are still useful!
Got my Bio Exam tomorrow for 1st year BA in Horticulture. Very helpful!! Thanks :)
i feel so so so much better about my biology final now!! mr. anderson is keeping me motivated. dont have to change my major lol
Great presentation, very clearly explained! Just one mention: :stomata" is the plural form. When you refer and show a single one, you should call it "stoma" instead.
The easiest way to explain the way in which water is sucked up from the roots and to the leaves is to think of the process in reverse. At the end of the waters journey the excess water found in the air spaces inside the leaf is released through the leaves stomata into the atmosphere, this water is then replaced by water evaporated from the surface of the mesophyll cells, this process causes a transpirational pull and lowers the cells water potential, this in turn allows for the mesophyll cells to take water from neighbouring cells through the waters potential gradient. This process of water loss connects back to the tracheids (water conducting cells found within Xylem) and causes water to be taken from the Xylem, this water then travels along the tracheids into the air within the leaf following the water potential gradient. Xylem travels up the stem of the tree by the action of a water potential gradient, water moves from an area of high potential, to an area of low potential, gradually moving water up from the roots. Waters natural cohesive and adhesive properties and the small diameter of Xylem aid in its movement up the stem.
Thank you for these videos! I use these as a review for my botany class because my professor doesn't go into much detail
EXCELLENT TUTORIALS PAUL, THANK YOU!!!
Amazing video! Summed up all the concepts in this particular area perfectly! Keep doing what you are doing because it is extremely helpful.
You’re a blessing to my biology grade.
I like your lectures so much
for the unloading of sucrose, it would have been nice if you would have explain the mechanism as well such as the use of hydrogen ion as co transporter etc...
Your videos are awesome! Thanks so much for helping us to understand science.
Hey Mr.Anderson... Thx for d video.... U made me understand.... Thnk u again
Bozeman i think you must have mentioned this point in like 3 words, or not but hope it helps you all 207,052 people or more.
Xylem vessels are single tubular vessels, so they transport water from the roots, to the stem and then the leaves for transpiration
'Phloem are multi tubular vessels, so they transport glucose around the plant and when stored, it converts to starch.
You are absolutely phenomenal.
You Sir have all my respect.
the best one! my teachers need to learn a lot from you too. thanks anderson for this amazing video
9:07 “You shall not pass” are the scariest four words you can say to someone before an exam
Thank you so much!
great video man. you make things easy to understand
You are the best. You are the saver of my life.
it's easier to study,explanations ar very clear
Congrats on 1 mil
YOU ARE AMAZING ...really thank you for doing this.. !!!!!
This video was very helpful. Thank you.
thank you for doing this
very great. thanks
Thanks so much for your awesome videos! So helpful.
It depends on the time of the year. We know carrots to be sweet because we harvest them in fall (after photosynthate has been partitioned to the root). If a carrot were left to overwinter, the starch would be hydrolyzed and then transported into the new leaves the following spring.
Love it.. its getting simple ..to understands
THANK YOU SOOOOOOOOOOOOOOOOOOO MUCH!!!
Thank you
Thank you for excellent work! It really helps!
Thank you so much for publishing these videos! You are helping me so much refresh my Bio knowledge :)
"YOU SHALL NOT PASS" LOL LOVELY
awesome, ty very much.
This 14 min video help me a lot 😄
Such an awesome explanation. Thanks!
Great video
I wish we had this level of Technology when I did Science at school - No wonder our kids are getting higher grades with the presentation capability available in 21st century!
this is so wonderful, really helped with my revision thank you so much
Do you believe that one can stimulate roots with electricity to boost productivity of growth?
Thank you! Your videos are so professional and ah-mazing! You should have a lot more views!!! :D
الشرح المبسط =يأتي من دراسه متعمقه
that tree has some serious girth !
Thanks!
better than my university professor
Thank you for the video, it was really helpful and ur explanations were easy to understand. :)
Superb.
Amazing! So helpful and clear, thank you so much for making these videos :)
This was helpful!
Thx for the video, it was really helpful. One thing that I don't get though: do roots ONLY use defusion? How do they absorb nutrients? The word "transport proteins" is moving through my head. And what about ions? How do plants absorb them?
Nice video. pretty much all your videos are nice:) helps me alot! thanks :)
love Gandolff for casperian strip
When you need a hero, this man is here
Very helpful to online students like me 😀
Learnt alot from you. Great vid!
Great video!
Very much appreciated!
You are the besssssssssst ever!!!!!!!
Very good for 7 years ago or perhaps all the better for it.
I'm looking at at the idea of optimising nutirient application by looking at a leaf under a microscope. Is this possible do you think?
Needless to say you can assess this from the point of view of the bottom leaves...... those are the first to be sacrificed...... but I want to take it stage further than that.
I want to be able to look at microcope slide and say I think I can wack on say another 25% or 10% feed to optimise plant growth with out causing root toxicity.
Thoughts anyone?
